小麦是印度的主要冬季作物,但大多数种麦区降雨量是有限的.为了最大限度地减少由蒸散(ET)亏缺引起的产量降低,实行可用水的限量灌溉是非常重要的.有证据表明,一定的蒸散亏缺的影响取决于亏缺发生的时间和它的强度(Hagan和Stewart,1972).由于小麦的根系分布和水分吸收模式密切相关(Chaudhary和Bhatnagar,1980),所以对供水有限的地区来说,根系分布广而深的植株可能是符合需要的. Wheat is India’s major winter crop, but rainfall is limited in most of the crops.In order to minimize yield loss due to evapotranspiration (ET) deficit, it is important to implement limited irrigation of the available water. (Hagan and Stewart, 1972). Since the root distribution of wheat is closely related to the pattern of water absorption (Chaudhary and Bhatnagar, 1980), the effect of water supply In limited areas, plants with broad roots may be desirable.
